Anionic polyacrylamide (APAM) is a water-soluble linear high-molecular-weight polymer, often used as a flocculant. It is characterized by its anionic (negatively charged) nature, making it particularly effective in applications where the removal of negatively charged particles or the flocculation of suspended solids is required.

Anionic Polyacrylamide Uses

Anionic polyacrylamide (APAM) finds widespread application across various industries due to its unique properties, particularly its negatively charged nature. Here are key applications of anionic polyacrylamide:

  • Water Treatment:

APAM has clarifying and purifying properties, promotes settling, aids in filtration, and enhances thickening. It is extensively utilized in the treatment of drinking water, industrial wastewater, mineral wastewater, and domestic sewage. APAM is primarily used in the purification treatment of wastewater ranging from weakly acidic to alkaline conditions. In addition, APAM is used for sludge dewatering to help reduce sludge volume and facilitate subsequent treatment and disposal during water treatment process.

  • Mining and Mineral Processing:

In mining operations, APAM is used for solid-liquid separation processes. It aids in the settling and dewatering of tailings and slurry, contributing to the efficient handling of mining wastewater.

  • Papermaking Additive:

Anionic polyacrylamide is employed in the paper industry to improve retention and drainage during the papermaking process. It aids in the formation of paper sheets and enhances the paper’s quality and toughness. 

  • Enhanced Oil Recovery (EOR) in Tertiary Oil Production:

APAM is utilized in the oil and gas industry for enhanced oil recovery processes. By increasing the viscosity of injected water, it improves the displacement of oil from reservoirs, leading to enhanced recovery rates.

  • Conservation of Water and Soil in Agriculture:

APAM is applied in agriculture for soil erosion control and stabilization. By improving soil structure, it helps in water retention and prevents runoff, contributing to sustainable agricultural practices.

  • Construction Industry:

In the construction sector, APAM can be used for soil solidification and foundation pit engineering to improve soil stability.
